Have you found a file with the extension .sfv and you don’t know what it is? doWhat is an SFV File? It is important to know how to open this file in order to work with it. In this article we will explain what is the file extension .sfvhow to open it and how to work with it.
What is an SFV File
The file extension .sfv comes from “Simple File Verification“, in Spanish “Simple File Verification”. The format of this miscellaneous file is a text format. There are currently 6 programs that can open the file .sfv on 3 different platforms.
The file .sfv is a simple text file, the CRC32 algorithm using a simple file detection function calculates the value for each file and a text file written to an .sfv.
After downloading the utility tool SFV for the downloaded file, the results are calculated and to compare files, if the file downloaded from a different program is wrong, you need to download it again.
And with a specific program to calculate a checksum or batch file, size, date and preservation.
CRC32: CRC itself is a means of “redundancy check”. CRC32 generates a 32-bit check value (8-digit hexadecimal numbers).
Since the CRC32 check value is generated for each bit of the source data block, the bits are involved in the calculation, the data block will give different CRC32 values.
MD5: Name of one of the message digest algorithms (also called a one-way hash function). A 32-bit hexadecimal, of which through a certain algorithm, according to each bit to finally produce a data source verification value of 128 (bit).
The most common application is MD5 cryptography, the paper mainly uses it to verify file integrity; if you find it difficult to understand the character, you can simply think of it as some kind of 128-bit MD5 digital signature for the school to check if the files have been modified.
SFV is most commonly used in RAR, MP3, ISO and other file formats.
What is the SFV File for?
Many of us download all kinds of files on the web, of course, providing a reliable streaming environment on the net.
But sometimes, due to various factors, the downloaded files are flawed and the original uploaders of the file are not exactly the same, making users often escape detection.
So the file cannot be determined from knowing if the file size is correct. Remember that the size of the original file and the downloaded file usually have no differences.
And there is no way to bring the original files, because the original file is in the distance on the Server, so this time if the other party has provided an SFV file, it is easier to deal with.
The presence of the SFV file serves to solve the above problems that arise at the file provider, when uploading the files. SFV software is used to generate a CRC for the file information, and it is recorded in a .SFV file.
While other users on the Internet at the same time also download this SFV file back to the computer, and then use the content of this file by SFV software to do CRC32 detection of other files.
Because the content of the file as soon as there is any change, its CRC32 checksum will be different, and thus the value of the information provided by the CRC. This means that the file downloaded on the Internet is not the same as the original file.
When we come to various well-known forums for FTP download, in each folder you can see that there is an SFV file extension of the file, what is it for?
In fact, it is a sub-volume compression packet inspection document, the role is used to check the cargo volume compression packet for errors, for FXP, this document is an indispensable component.
